Staph or mrsa. do i need antibiotics?

From your question above it can be several types of bacterial infection or maybe allergy. You must detect real cause of your health issue. Did you think that you're maybe allergic to something? It would be best to visit dermatologist and do some tests to see what really is your problem. You must be persistent in your efforts, because some of tests are expensive and doctors order them only if it is emergency. Good luck!
